Description

Consider the following:

File fooDir = new File("/temp/foo");
File fooFile = new File("/temp/foo.txt");
FileUtils.directoryContains(fooDir, fooFile); // returns true, should return false

fooFile is a sibling of fooDir. fooDir does not contain fooFile.

This is due to the way FilenameUtils.directoryContains is implemented in that this method uses a simple 'startsWith' comparison. A related bug is filed for the FilenameUtils method that I believe should be fixed as well.
